If you can’t submit a ticket update in Zendesk Support, follow these steps to troubleshoot the issue. 

  1. Open Zendesk Support in an incognito or private browser. If you can submit your update, clear your browser's cache and cookies. Then, reload Support and try submitting your update again.
  2. Browser extensions or plugins might interfere with ticket submission. Disable them one by one to see if any are causing the issue.
  3. Add ?noapps to the end of the ticket URL. This helps identify if apps on your Zendesk account are blocking the submission. If the update goes through, disable the apps one by one.

  4. If an app prevents you from updating a ticket, reach out to the app's developer for support. For more details on troubleshooting the Apps framework, check the article on Debugging the Zendesk Apps framework (ZAF).
  5. If none of these steps work, contact the Zendesk support team. Include a HAR file for further investigation.
